My family enjoys kefir, which is widely known for its health benefits. You can find it in almost any grocery store, and a bottle isn't too expensive. However, I started to wonder if it might be better to make my own kefir at home. At first I thought it was just yogurt with milk added to thin it out. After doing some research, I discovered that making kefir is surprisingly easy to make and super cost effective.
Kefir’s origins date back over 2,000 years, believed to have started in the North Caucasus region, located between the Black Sea and the Caspian Sea, in what is now Russia, Georgia, and Armenia. Here's a look at its history and development:
Origins:
- Caucasus Tradition: Kefir was initially made by local herders who discovered that fresh milk carried in leather bags would naturally ferment due to the presence of kefir grains. These grains are a combination of lactic acid bacteria, yeasts, and polysaccharides, which work together to ferment milk into a thick, tangy beverage. The specific microbial mixture is unique to kefir grains and is passed down through generations.
- Legend of the "Grains of the Prophet": According to local legend, kefir grains were a gift from the Prophet Muhammad to the people of the Caucasus. They were considered to have divine properties, and their recipe was closely guarded. This secrecy contributed to the slow spread of kefir beyond the region for centuries.
Spread to Europe and Beyond:
- Russia and the Caucasus: For centuries, kefir remained relatively unknown outside the Caucasus region. It became more widely known in the late 19th and early 20th centuries when Russian doctors began to recognize its health benefits, particularly in treating digestive issues like tuberculosis and gastrointestinal disorders. In the early 1900s, kefir production began on a small scale in Russia.
- Western Popularity: Kefir gained further prominence in Western Europe and North America in the 20th century as interest in probiotics and fermented foods grew. The demand for natural, healthy foods increased kefir’s popularity outside its original cultural context, and it began to be mass-produced and sold commercially in health food stores and supermarkets.
Health Benefits of Kefir
Kefir is not only delicious but also packed with health benefits, making it a great addition to your daily diet. Here's why:
- Rich in Probiotics
Kefir is a natural source of probiotics—live bacteria that benefit your digestive system. These beneficial microorganisms help balance the gut microbiome, improve digestion, and enhance immune function. Some research suggests that probiotics in kefir may also help prevent and treat diarrhea, especially after antibiotic use. - Improves Digestive Health
The probiotics in kefir not only promote a healthy gut but also help reduce symptoms of gastrointestinal conditions such as irritable bowel syndrome (IBS) and Crohn’s disease. Regular consumption can support smoother digestion and may alleviate bloating and discomfort. - Boosts Immune System
Kefir helps stimulate the immune system, reducing the likelihood of infections. It also contains lactoferrin, a compound known for its antiviral and antimicrobial properties. - Supports Bone Health
A great source of calcium and vitamin K2, kefir plays a vital role in maintaining strong bones. Vitamin K2 helps direct calcium into the bones, reducing the risk of calcification in the arteries. Consuming kefir may lower the risk of osteoporosis and improve bone density. - Anti-inflammatory and Antibacterial Properties
Some probiotic strains in kefir can reduce inflammation in the body. Kefir also has antibacterial properties, which may help fight harmful bacteria like Salmonella and E. coli. This makes it a valuable addition to your diet for overall gut and immune health. - Improves Lactose Digestion
If you're lactose intolerant, kefir may be easier to digest than regular milk. The fermentation process breaks down most of the lactose, making it a more tolerable option for those with lactose sensitivity. - Promotes Heart Health
The probiotics and bioactive compounds in kefir may help reduce cholesterol levels and blood pressure, two key factors in maintaining heart health. Studies suggest that regular kefir consumption can contribute to improved cardiovascular health. - Antioxidant Properties
Kefir contains antioxidants that help fight free radicals, reducing oxidative stress and the risk of chronic diseases like cancer, diabetes, and heart disease.
Making Kefir at Home
Once I decided to try making kefir at home, the first thing I needed to figure out was how it’s made and how much effort it would take. To my surprise, the process is incredibly simple, and you only need a few basic items to get started. The most important thing to note is to avoid using metal tools or containers, as this can lead to metal leaching into the kefir.
Here’s what I recommend for getting started:
This will cost about $30-$40 upfront, but the long-term savings are substantial. At the time of writing, a gallon of milk costs around $3, and a quart of kefir is priced at about $3.89. Since there are four quarts in a gallon, buying kefir by the quart would cost you $15.56 per gallon. By making your own, you'll save $12.56 per gallon after the initial cost of supplies. So, after making just three gallons, you should have recouped your investment.
Step-by-Step Instructions
- Getting Started
Begin by adding the kefir grains to one of your quart jars. Fill the jar halfway with milk, then loosely cover it with a plastic lid. If you're using a metal lid, use just the ring and a coffee filter to cover the jar instead of sealing it completely. Let the jar sit at room temperature for about 24 hours. The first batch may not show much activity, but it will still be fermenting. Be sure to strain and save the kefir grains for the next batch. - Running Batches
After the initial batch, subsequent batches typically take between 12 to 18 hours. You'll know the kefir is ready when it smells slightly tangy. If you see clear liquid separating from the kefir near the bottom of the jar it’s pretty much done. If you cannot deal with it right, just stick it in the fridge until later. If it goes longer, it’s still usable. Pour the liquid through the funnel into a clean container, using a plastic spoon or chopstick to help clear any blockages in the funnel if needed. Transfer the kefir grains to a fresh jar, add more milk, and repeat the process. - Storing the Grains
If you need to take a break from kefir-making, you can store the grains in the fridge for up to three months. Simply keep them in a jar with milk. When you’re ready to start again, give the grains extra time to ferment the next batch.
Final Thoughts
Ideally, kefir is made with raw milk, but most of us don’t have access to that. You can use any milk that is not ultra-pasteurized. Also, you may notice that what you get will be thinner than what you get in the store, but that will improve as the grains get bigger. With just a bit of practice, you can make your own healthy kefir at home without spending more time or money than necessary. It’s a win-win!
